TPS25940-Q1  
SLVSDJ0D –MAY 2016–REVISED SEPTEMBER 2018  
TPS25940x-Q1 2.7-V to 18-V eFuse with Integrated Short-to-Battery Protection  
1 Features  
3 Description  
The TPS25940x-Q1 eFuse Power Switches are  
compact, feature rich power management devices  
with a full suite of protection functions. The wide  
operating range allows control of many popular DC  
bus voltages. Integrated back-to-back FETs provide  
bidirectional current control making the device well  
suited for systems with load side holdup energy that  
must not drain back to a failed supply bus.
